Abstract

PURPOSE:To obtain a soil mixer for rice transplanter, having a rotating drum and concentric circular arc bottom plate with an interval from the above- mentioned drum on a frame and constituted so as to take out mixed soil with the aforementioned circular arc bottom plate and capable of reducing load on a motor in taking out the mixed soil. CONSTITUTION:An opening and closing lid 14 is removed to charge soil and a fertilizer from an inlet and outlet 13 to almost half in a rotating drum 6. The inlet and outlet 13 is then closed with the opening and closing lid 14 and a motor 27 is operated to rotate the drum 6 in the direction (a). Thereby, the soil is homogeneously mixed with the fertilizer to prepare mixed soil 12. The rotation of the drum is subsequently stopped to remove the lid 14 and the drum 6 is further rotated to drop the mixed soil 12 from the inlet and outlet 13 into a space part 6 when the inlet and outlet 13 reaches the under side. About half of the dropped mixed soil 12 is then discharged from a discharging port 17 to the outside of the mixer by the first scraping out unit 19 and the residual soil is discharged from the discharging port 17 to the outside of the mixer by the second scraping out unit 24. As a result, the mixed soil 12 in the space part 16 is taken out of the frame 1 in two stages.

The sprocket is a sprocket fixed to the end of the rotation center shaft 10, and is wound between the sprocket δ and the sprocket δ fixed to the rotation shaft n of the motor n.

Reference numeral 31 indicates an encircling cover that surrounds the chino (material), casters are attached to the lower surface of the rear side of the frame l, and wings are handles.

(effect) Next, we will discuss the effect.

Since the present invention has the following configuration, the opening/closing lid 14 is removed to open the entrance/exit 13, approximately half of the soil and fertilizer are poured into the rotating drum 6 through the opening/exit 13, and then the opening/closing lid 14 of the entrance/exit 13 is opened. When motor n is energized,
The rotating drum 6 starts rotating in the A direction about the rotation center axis 10.

Since a plurality of stirring wheels 15 are installed inside the rotating drum 6, the soil and fertilizer at the bottom are scooped up by the stirring blades 15 and then fall down, and this process is repeated to evenly distribute the soil and fertilizer. Mixed to result in a mix of ±12.

After rotating the rotary drum 6 for a predetermined period of time, the rowing is stopped, the opening/closing lid 14 is completely removed, and the entrance/exit opening 1 is completely removed.
3 is open, when the motor n is energized again to rotate the rotating drum 6, the lower half of the rotating drum 6 is surrounded by the left side plate 3, the right side plate 4, and the arcuate bottom plate 5 of the frame 1. Since a space 16 is formed between the outer circumferential surface of the cylinder 7 of the rotary drum 6 and the top surface of the arcuate bottom plate 5, when the entrance/exit 13 reaches the lower part, the rotary drum 6 is removed from the entrance/exit 13. The mixed soil inside falls into the space 16 (Fig. 5).

Therefore, the outer peripheral surface of the cylinder 7 and the entrance/exit 1
A first scraping body 19 in the left-right direction is attached to the rotating downward side of the cylinder 3, and a second scraping body 24 is provided on the outer peripheral surface of the cylinder 7 on the opposite side of the first scraping body 19. - Since the scraping body 4 is formed of a round bar, the mixture ±12 that has fallen into the space 16 from the entrance 13 is first discharged outside the machine from the half mixer discharge port 17 by the first scraping body 19. Then, the second scraper 24 discharges the remaining soil from the mixing top discharge port 17 to the outside of the machine, creating a space in two stages! Scrape out the mixed ± vases within 6.

Therefore, the first scraped body! 9 and the second scraping body 24 to scrape out the mixed retainers in the space 16 in two stages.
The first scraping body 19 does not need to splash all the mixed soil l that has fallen from the entrance/exit 13 onto the arcuate bottom plate 5-H, and takes out about half of it outside the frame l. The load can be reduced.

In this case, the first scraping body 19 is formed of a round bar, and there is a gap 22a between the first scraping body 19 and the top of the arcuate bottom plate 5, and a gap 22b between the first scraping body 19 and the outer peripheral surface of the cylinder 7. is formed, the gap 22a and the gap 22b serve as an escape,
It is possible to reduce the impact when the first scraping body 19 enters the mixing position 12, and the load on the motor n can also be reduced.

Therefore, when the rotary drum 6 is rotated, the tip of the second scraping body 24 is mounted as close as possible to the edge of the arcuate bottom plate 5 without sliding into contact with the edge of the arcuate bottom plate 5. All the remaining mixed soil 12 can be taken out of the frame l. In addition, since the second scraping body 24 is attached to the support plates δ, δ with a receding angle, the impact when it comes into contact with the mixed soil can be reduced, and the load on the motor n can also be reduced.

In this case, since the arcuate bottom plate 5 is formed in an arcuate shape that is lowest at the center and gradually becomes higher toward the front when viewed from the side, the first scraping body 19 and the second scraping body 24 Since the scraped mixture ±12 is blown away to a location away from the frame 1, it is easy to utilize the mixture leakage.

(Effects) Conventionally, as shown in FIGS. 8 to 10, a rotary drum C rotates on a horizontal axis rotated by a motor D, and a frame A surrounding and pivoting the lower half of the cylinder E of the rotary drum C. The frame A is provided with a bottom plate, the outer circumferential surface of the rotating drum C is formed with an entrance G having a removable opening/closing lid F, and the outer circumferential surface of the rotating drum E is provided with the entrance/exit G. A soil mixer for seedlings for a rice transplanter is known which is provided on one side with a scraping body H made of a plate that scrapes out the mixture I on the bottom plate that has fallen from G at one time. The above-mentioned known ones.

a. Since the mixed soil I in the frame A is scraped out with one scraping body H, the motor D that rotates the rotary drum C becomes large-sized.

b. Since the load on the motor D is large, the rotation of the rotating drum C is slow, and it takes time to take out the mixed ±I.

C. Since the bottom plate of the frame A that also serves as a case is formed flat, the scraper H cannot remove all of the mixture ±1.

There is a problem.

However, in the present invention, since the frame 1 is provided with the arcuate bottom plate 5 concentric with the rotary drum 6 at a distance from the rotary drum 6, the mixed soil can be guided out of the frame 1 by the concentric arcuate bottom plate 5.

Further, on the outer circumferential surface of the one-rotation drum 6, a third scraping body 19 consisting of a rod is disposed to scrape out the mixture of the arcuate bottom plate 5J that has fallen from the entrance/exit 13 in two parts, and Since the second scraping bodies 24 are provided at an interval of 180 degrees, the mixed soil can be thrown away without imposing an excessive load on the motor n, making it easy to use.
